Some Famous PLC Brands
There isn’t a single PLC brand or model that is universally used in all industries. The choice of PLCs often depends on the specific requirements of the application, the industry, the cost, and the preferences of the engineers or system integrators involved. However, some of the well-known and widely used PLC manufacturers include:
- Siemens
- Allen-Bradley (Rockwell Automation)
- Schneider Electric
- Mitsubishi Electric
- Omron
- ABB
- Delta Electronics
Each of these manufacturers offers a range of PLCs with different features, capabilities, and programming languages. The choice of PLC depends on factors such as the complexity of the control system, communication requirements, scalability, and the specific needs of the industrial process.
In today’s industrial automation scene, many companies are racing to make their mark by manufacturing their PLCs. The big players like Siemens, Mitsubishi Electric, ABB, Schneider Electric, Hitachi, Panasonic, and Fuji Electric are not just making PLCs but have become major conglomerates in the field.
Others like Rockwell Automation, Omron, Keyence, Unitronics, Fatek, Idec, and Yokagawa are sticking to specializing in PLCs and related automation gear.
The industrial automation landscape is changing, with some PLC makers coming and going, and others merging to stay competitive. Some have added PLC brands to their lineup through acquisitions. Brands like General Electric (GE Fanuc), Telemecanique, Square-D, and Cutler-Hammer were big PLC providers in the past but are no longer active, making room for the next-gen PLCs.
